TINNERS' FlRE-POT.,

SPECIFICATION forming part of Letters Patent No. 269,577, dated December26, 15582,

A pplication filed October 18, i882.

To all whom it may concern of the United States, residing at Baltimore,Maryland, have invented new and useful Improvements in TinnersFire-Pots, of which the following is a specification.

My invention relates to that class of tinncrs tire-pots which are heatedby the flame producrd by vaporizing gasoline, petroleum, or kindredfluids by means of heat, said fluid being supplied to the burner underpressure by air forced into and compressed in the fluidsupply tank by anair-pump operated by hand or any convenient power; and the points ofnovelty will be first fully described, and then pointed out in theclaims.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical section through my tire-pot and a burner, a supply-tankand pump being also shown in elevation therein,a portion of the tankbeing broken away to show a portion of its interior. Fig. 2 is a frontelevation of my fire-pot and burner. Fig. 3 is a side elevation of myfire-pot. Fig. dis a side elevation and perspective of the grate, andFig. 5'is a section and an elevation of the deflector.

Y Like letters refer to the same parts in all the figures.

My fire-pot is composed of two or more globular chair'ibers, which I,for convenience, call stories, there being two shown in this instance,of which Ais the lower and A the upper one, the latter being supplied atthe top with a chimney, A and the former with an openingin thebottom,1eading to the hollow base A On one side of the main story A isan opening, a, to receive the end of aretorttube attached to a burner,and on its opposite side is an opening, a, to admit air to the rear ofthe deflector B. The bottom opening of this chamber or main storyAispartially closed by a grate, U. The fire-potis composed of two verticalsection's, B B which are eachprovided with lugs b perforated to receivebolts, by which they are fastened together. The base A is provided witha box or drawer, a to receive any waste solder that may drop from theirons. In the front of each chamber A A,

concavo-convex in section, and isprovided with pins 1), one at top andone at bottom thereof, which are fitted into halt-perforations or semi-4 cylindrical grooves b in the sections B B, which grooves and pins areset at an angle of about forty degrees to the vertical, thus securelyholding the deflector in place when the sections are secured together.The deflector is also provided with a semicircular notch on each side toadmit of a free circulation of air when in place in the fire-pot.

The burner is composed of substantially a tube, 1), having in it aneedle, D, adapted to open or close an orifice, D to admit the "aporizedfluid into the retort-tube D The retort-tube is perforated, as. at d, toadmit air and to prevent any palpitating combustion by reason of suddendrafts or gusts of air striking into said openings. They are protectedby a hood or outer pipe, D. The joint d of the burner, being made ofcopper, is a very good portion (1 is made of iron. Below the burner is acup, (1 to receive a small portion of oil, with which to heat the burnerto start the vaporization. It maybe utilized also to receive any wasteoil which may drip from the burner.

E is the supply-tank, provided with a safetyvent, e, and an air-pump, F.The air being forced from the pump through pipefinto the tank forces theoil up through the pipe 0 to the burner. The fluid passing up to theburner under pressure is vaporized in the burner and the vapor lightedin the retort-tube. The air passing into said tube through the openings(Z intensifies the heat, and the flame passing into the chamber A isthrown back by the deflector B, fills the chamber A, and passes upward,filling the upper chambers.

The soldering-irons to be heated are laid in through the openings in thefront of thechamhers, and when it is desired to increase the ca pacityof the fire-pot rods are passed in'through openings a whereby a doublelayerof irons may be placed in the chamber and heated.

The deflector B is circular in outline andconductor of heat; and inorder to keep the back part of the burner as cool as possible the Whenthe irons are in use considerable solder adheres to them and is meltedofi'when they are reheated. This waste has heretofore amounted to aconsiderable item, and in my deviceis entirely avoided, the box ordrawer a catching all waste solder, which, when it leaves the irons,will drop through the opening in the bottom of the chambers into saidbox or drawer. The deflector Bis kept cool to a certain extent by theair which enters the chamber behind the deflector through the opening a.

' Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, isv l. The fire-pot composed of twosections, BB united in a vertical plane and bolted to gether, each section beingcomposed of a base and a-series of hemispheres opening into each other,as and for the purpose set forth.

2. The combination, with the sections B B havingsemi-cylindricalgrooves, of the deflector B, having pins 0 set at an angle, as shown.

3. The fire-pot consisting of base A and globular chambers A A, havingcom municating openings and chimney A in combination with deflector Band grate-bar G, substantially as set forth.

4. The fire-pot constructed substantially as described, with globularchambers A A, having openings in their tops and bottoms, the

base-chamber A and the receptacle M, whereby waste solder from all thechambers is collected in said receptacle, as set forth.

5. The fire-pot having globular chamber A, the walls thereof havingopenings c and a door or opening of sufficient vertical dimensions toadmit a num her of soldering-irons one above the other, for the purposeset forth.

6. The combination, with the fire-pot constructed, as described, withcommunicating chambers of globular form, of the burner and oil-supplyand suitable air-compressing apparatus for forcing the oil in to theburner.

7. The combination, with the fire-pot having globular chamber A, thewalls thereof being provided with openings a and a, of the deflector,constructed as described, and the oppositely-located'retort-tube, andsuitable apparatus for forcing the flame into the chamber against saiddeflector, as set forth.

8. The combination, witlrthe fire-pot having globular chambers A A andopening a, of the retort-tube inserted in said opening, the burner, afluidsupply, and suitable air-forcing apparatus, as set forth.

In testimony whereof I subscribe my name.
